LG has registered three trademarks LG G Flex Frame, LG G Frame and LG F Frame in the U.S. Patent and Trademark Office. LG G Flex Frame should be a new product of LG G Flex series. Of course, what's more remarkable is that these three models all bear the trademark of Frame, does it mean that there will be new surprises on the border? Could it be the recently popular Master Jin frame? It seems that LG doesn't have many metal machines.
